somatosensory evoked potential

somatosensory evoked potential
(SEP) waves recorded from the spinal cord or cerebral hemisphere after electrical stimulation or physiological activation of peripheral sensory fibers; analysis of deviations in latency or amplitude can detect or characterize lesions of the peripheral or sensory conduction pathways.
